QDB300 - Western Enterprises QDB300 Inert Gas Quick Connect Set

Technical Overview of the Western Enterprises QDB300

The Western Enterprises QDB300 is a precision-engineered Quick Connect set designed specifically for the interface between gas regulators and hoses in inert gas applications. Manufactured in the United States, this component is constructed from high-grade brass, ensuring exceptional durability and resistance to corrosion in industrial environments. The unit is engineered to facilitate rapid connection and disconnection of gas lines without the need for tools, significantly reducing downtime during equipment setup and maintenance.

Technically, the QDB300 is rated for a maximum pressure of 200 PSIG, making it suitable for a wide range of inert gas delivery systems, including Argon, Helium, and Nitrogen. A critical safety feature of this device is the integrated reverse flow check valve. This mechanism is calibrated to provide instant closure and total shutoff upon detecting as little as 10 ounces of back pressure, effectively preventing dangerous backflow conditions. Furthermore, the connector geometry is specifically keyed to be non-interchangeable with oxygen or fuel gas connectors (CGA 032 standard), thereby eliminating the risk of cross-connection and accidental gas mixing.

Reliability is a cornerstone of the QDB300's design. The internal mechanism has been cycle-tested to withstand over 100,000 connect/disconnect operations. Based on comparable usage data, this translates to a projected service life of 10 to 12 years, offering substantial long-term value for facility managers and safety officers. The fittings utilize standard B-Size 5/8"-18 UNF Right Hand threads, ensuring compatibility with the vast majority of industrial regulators and hoses used in welding, laboratory, and manufacturing sectors.

This assembly includes both the female body (typically attached to the regulator) and the male plug (attached to the hose), providing a complete solution for upgrading standard threaded connections to a high-efficiency quick-connect system. Its compact design, with a hex width of 3/4 inch, allows for installation in tight spaces without compromising accessibility.
